In the present day, a demon emerges through the Sacred Tree at Higurashi Shrine with Setsuna, Towa’s twin, and the bounty hunter Moroha in tow. Towa, Setsuna, and Moroha struggle to battle the demon, whose powers have been strengthened with two Rainbow Pearls, but seeing Setsuna in trouble awakens Towa’s latent demon powers.
You said "twins." That means 
there's another child out there?
قلتِ "توأميه". هذا يعني أنّ هنالك طفلًا آخر في مكان ما؟
Wenn sie Zwillinge waren, muss es
ein weiteres Mädchen geben, nicht?
Si son gemelas, eso significa
que hay una hija más, ¿verdad?
Si eran gemelas,
debe tener una hermana, ¿no?
Si elle avait une jumelle,
elle est quelque part.
Se erano gemelle...
vuol dire che c'è un'altra figlia, giusto?
Se são gêmeas,
quer dizer que há outra filha, certo?
Вы упомянули близнецов. 
Значит, есть и второй ребёнок?
